Fibre Humidity Sensor

A new fibre grating humidity sensor is now available at O/E LAND INC. The new sensor OEFHS-100 is based on a patent pending technology and profits from our advanced fibrr Bragg gratings know-how. Fibre grating humidity sensors are used to measure the relative humidity (RH) in a wide range with high accuracy and sensitivity. An optional temperature sensor can be built in with humidity sensor for monitoring both humidity and temperature at the same time.

Although individual humidity sensors can be used in various applications, O/E Land Inc offers humidity sensor arrays in which multiple FBG sensor are written in the same optical fiber.
